THK SHS45-570L Linear Guide Rail

The THK SHS45-570L Linear Guide Rail delivers precise, high-rigidity linear guidance for 570 mm of travel within a 45 mm rail profile, ideal for automation equipment and robotic systems where repeatable positioning matters. Maintenance teams and system integrators rely on this rail for machine repair, retrofit projects, equipment upgrades, and replacement of worn or damaged linear guides, thanks to its four‑way equal‑load design and caged ball LM guide compatibility with THK SHS45C, SHS45LC, SHS45R, and SHS45V blocks. Key specs include a 45 mm rail size and 570 mm rail length, with a 45 mm width and 37.5 mm height; standard hole pitch 105 mm, end distance 22.5 mm, mounting hole size 14 × 20 × 17 mm, and M14 mounting screws mounted from above; it is made from hardened bearing steel with a surface hardness of 58–64 HRC and supports grease or oil lubrication, with a maximum standard rail length of 3090 mm. Common applications span CNC machine tools, factory automation systems, electronics manufacturing equipment, robotic positioning, material handling machinery, medical equipment, and automated inspection or assembly machines where high rigidity, low friction, and long service life are essential; reference number #202717.
